With the changes in the South African political and economic climate in the past years, an increase in violent crime has become one of the most significant issues affecting the people of this country. Among them is car hijacking, which has reached epidemic proportions. As a result of this traumatic experience, many of the victims of hijacking develop posttraumatic stress disorder or symptoms thereof. From the literature it would seem that certain . variables may increase the vulnerability for the development of this disorder. This study sought to investigate a number of these variables, namely, demographic information, attributional style, personality style, and both premorbid depression and anxiety. The purpose was to establish whether pre-existing risk factors, that were found in the literature to play a role in the development of PTSD, also apply to the South African population, as well as to victims of car hijacking specifically. As this situation is unique to South Africa, there is a great need for information in this area. If these risk factors could be isolated, more effective treatment may be
developed for victims. A sample of 38 hijack victims was approached to complete a battery of psychometric tests to assess the above mentioned variables as well as a measure of posttraumatic stress syrnptomology. The Revised Impact of Events Scale, Attributional Style Questionnaire, Millons Clinical Multiaxial Inventory, State-
Trait Anxiety Inventory and Beck Depression Inventory were used as psychometric instruments for this study. Inferential statistical analyses as well as descriptive statistical analyses were performed on the data. In general, no specific constellation of premorbid factors contributing to the impact of the event were found. Depression and state anxiety showed significant contribution to the impact of the hijacking but these variables measured current symptoms rather than premorbid. No other variables proved to be significant. This result may have been strongly influenced by the fact that the sample was very homogenous. The findings therefore offer difficulties as far as generalizability is concerned. It is recommended that this study be performed on a larger, more representative and diverse sample in the future.
